Since installing 17.12.1.....which was a pain in the arse like every other driver update.
I boot into safe mode and use the AMD Clean Uninstall and then install the driver.
Every time I reboot, approx 3 minutes after logging in one of my Vega 64's indicator light goes off and the fan spins at 100%. Freezes the computer, I have to shutdown via the Case's Off button.
Generally the second or third reboot its ok and working fine.
If I reboot again, I have to go through the same procedure.
Any ideas? Thanks for your help.
